Therefore, it is of great importance that the decision-making process is set up in the interest and satisfaction of the cancer patient. In a survey of 2,011 patients aged\u2009\u2265\u200950 years with breast cancer or colorectal cancer, 72.1% reported high satisfaction with the treatment decision-making process. Multivariate logistic regression identified several independent predictors of higher satisfaction: receiving comprehensive information about the illness and therapy options (adjusted odds ratio (aOR) 5.37, 95% CI 3.89\u20138.52), strong personal involvement in decision-making (aOR 2.93, 95% CI 2.15\u20133.98), perceived concordance among treating physicians (aOR 2.01, 95% CI 1.49\u20132.71), higher self-efficacy (aOR 1.63, 95% CI 1.31\u20132.04), and greater social support (aOR 1.36, 95% CI 1.10\u20131.67). Conversely, frailty was associated with lower satisfaction (aOR 0.66, 95% CI 0.48\u20130.90). These findings suggest that patient satisfaction with decision-making may be enhanced when physicians provide thorough information, actively involve patients in decisions, and coordinate care consistently, while frail patients and those with low self-efficacy or limited social networks may benefit from targeted support.<\/jats:p>","DOI":"10.1038\/s41598-026-51157-y","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T20:27:37Z","timestamp":1777580857000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Communication-related aspects drive senior patients\u2019 satisfaction with the process of decision-making in cancer therapy"],"prefix":"10.1038","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3279-416X","authenticated-orcid":false,"given":"Andreas","family":"Heidenreich","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rabea","family":"Fuchshofen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7678-7071","authenticated-orcid":false,"given":"Susanne","family":"Elsner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6409-3822","authenticated-orcid":false,"given":"Frank","family":"Gieseler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0490-1554","authenticated-orcid":false,"given":"Alexander","family":"Katalinic","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8596-2046","authenticated-orcid":false,"given":"Joachim","family":"H\u00fcbner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"51157_CR1","unstructured":"Medicare: New Directions in Quality Assurance: Proceedings of an Invitational Conference (National Academy Press, 1991)."},{"key":"51157_CR2","doi-asserted-by":"publisher","first-page":"2221","DOI":"10.1001\/jama.1992.03480160079038","volume":"267","author":"EJ Emanuel","year":"1992","unstructured":"Emanuel, E.
